scte35dump

从文件或RTP网络流中转储SCTE-35数据

USAGE:
    scte35dump [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    file       Read a transport stream from the named file
    help       Prints this message or the help of the given subcommand(s)
    net        Read an RTP-encapsulated transport stream from the network
    section    Decode a single splice_info section value given on the command line

安装

1. 安装rustup: https://rustup.rs/（它将为您提供一个Rust构建环境，包括cargo工具）
2. 运行cargo install scte35dump
3. 运行scte35dump --help以获取使用说明

SCTE-35规范覆盖范围

并非所有命令都已实现

• splice_null()
• splice_schedule()
• splice_insert()
• time_signal()
• bandwidth_reservation()
• private_command()

示例

file子命令

从本地传输流文件中转储

scte35dump file test-dump.ts

net子命令

从RTP多播流中转储（添加--udp选项以使用未封装RTP的纯UDP）。
